What is mChapters

mChapters is a simple, intuitively and easy-to-use chapter marker editor for MP4/MOV files. Chapter markers will make it easy for users to skip a playing-time to a specific time. It's very useful especially in long duration videos and audios.

mChapters saves chapter marker times and titles as a text track into a file. The text track format is defined by the QuickTime/MP4 specification.
In Mac, you can use chapter markers in QuickTime Player, iTunes and other apps which support the format.
In iOS devices, you can use chapter markers in apps which support the format. But Apple's Music app and TV app does not support it.

mChapters does not re-encode audio/video data when saving. That does not affect the qualities, and that makes completing a quick save.

System Requirements

macOS 10.12 or later

Supported formats

mChapters cannot open files which require any conversion or codec components in QuickTime Player, and protected videos (e.g. Movies, TV Shows downloaded from iTunes Store).
